Abstract

We have been studying the chicken lysozyme locus as a model to examine the prerequisites for the establishment of a transcription competent chromatin structure. We recently discovered a new enhancer element located at 3.9 kb which is activated early in macrophage differentiation. The chromatin of the 3.9 kb enhancer exhibits an unusual structure, since its activation leads to nucleosome phasing over 3 prime flanking sequences. In vivo DNA-protein interaction studies demonstrated differential binding of transcription factors. In this proposal we wish to answer the question, whether specific factor(s) and/or a specific DNA-structure is responsible for the precise positioning of nucleosomes after enhancer activation. We wish to examine the molecular basis for the tissue specific activity of this interesting cis-regulatory element.
